Prince John is the youngest of George V and Queen Mary's six children, born in 1905 and diagnosed with epilepsy as a small boy. The popular story, repeated for decades, is that the royal family hid him away as an embarrassment and cut him off from his siblings until he died in 1919 after a severe seizure, aged thirteen. This film tests that story against people who actually knew him, tracking down individuals with direct personal connections to John and pairing their testimony with newly surfaced photographs and archival research. The picture that emerges complicates the neglect narrative without denying the isolation he lived through, showing a child who was both shielded and, in real ways, shut out. Had he survived, John would have been an uncle to the present Queen, a detail the film uses to underline how close this obscured life sits to the royal family's public history. It is less interested in scandal than in correcting the record with evidence rather than assumption.
